A lot of people put Extraterrestrial life into the same catagory as Big Foot or Loch ness Monster...As in Shii that doesn't exist.

Theres billions of Galaxies...Billions of stars in each Galaxy including our own... and its believed that for every star theres atleast 1 planet(usually more), which means that theres hundreds of billions of planets in our Milky Way Galaxy alone. Even if the chance for a planet to contain intellegent life is 1 in 1,000,000, that leaves us with hundreds of thousands of planets. With all this being said... WHY DO PEOPLE NOT THINK ALIENS EXIST? -_-

I think most people believe that alien life exists... Unless, they are deeply religious, and believe the earth is the only experiment of god, or something... Which, I'll never understand...

What most people put in the category of bigfoot... Is abduction. Have aliens just stopped coming here since the invention of the cell phone camera? Why is there never very compelling evidence, in this world of instant light speed communication?

I think alien life exists, i'm just not sure it can move faster than the speed of light, so they might simply be uninterested in us as a species. If I was an alien, with a light speed ship, I wouldn't think humanity was evolved enough for a visit yet. I'm not a fan of vivisection.

It could also be that there are no other life forms out there because an alien race have killed each other due to the existence of weapons of total mass destruction falling into the wrong hands.

If alien existence were to be disclosed, that would bring about a whole bunch of problems for the people who bring in hundreds of trillions of dollars each year in the energy business. Why? Civilizations way more advanced than us would not be using fossil fuels to power their ships across the galaxy. If humans were to get ahold of this technology and spread it out for everyday use, these huge energy companies would be obsolete.

Ignorance: most people don't even know the difference between a solar system and a galaxy, most people that do know it from watching science fiction, but don't know how bloody big a galaxy is and how many galaxies there are in the universe.

Your question is why do people NOT think... See? You answered your own question.

Many fundamentalist Bible-based religions cannot accept it because (only one example) if the Universe/Multiverse is so grand, why did God choose earth as the place he put his only son to be tortured to death. Why not on some other planet? Because the earth is the center of the universe/multiverse, and God lives somewhere in earth's atmosphere, that's why!

Life as we know it on earth has its specific appearance due to local circumstances and earth's history.
If something similar would happen on another planet everything will be different we even may not recognize it directly as something like living organisms. It could even not be based on carbon and hydrogen and composed from different elements.
The kind of energy source and the kind of dynamics that things move around on or under the surface of that planet and its atmosphere as also the structure and elements present, determines in what way a planetary consciousness develops.

Maybe Jupiter is more alive than we think it is but how can we know?

So for life as we know it here on earth many things has to be similar. The size of the sun and planet as well as their their distance has to be the same. It has to have a moon that gives a good pull as the planet rotates on a tilted ax. In short, it has to be almost completely similar to earth to produce anything that we would call an alien.

Planets that have roughly the same mineral composition and gravity as Earth have been observed, I believe one of them was even in its star's habitable zone adn we have only looked at a small percentage of all the stars in only this galaxy...
